Amethyst Imbuement

Fixes:

• Fixed jewelry letting you add more than one augment.
• Fixed multilevel augments.
• Fixed Empowered Slash recipe not showing up.
• Fixed a myriad of minor issues with the Glistering Tome guide.
• Fixed glowing pick LambDynamicLights registration.

Changes:

• Re-implemented imbued jewelry's innate shielding as well as the Shielding augment. No longer provides absorption. Instead has a small, stacking chance of completely blocking an attack. Max chance with all 4 trinkets all with Shielding III of approx 1 in 3 attacks blocked.
• Increased level requirement for spectral slash.
• Changed Altar of Experience recipe to be more in line with the other altars and also to increase progression difficulty slightly.
